MACHINE FOR BENDING FELLIES.

Speccaton of Letters Patent No. 21,351, dated August 31, 1858.

T0 all 107mm t may concern:

Be it known that I, JOHN L. MANN, of Ravenna, in the county of Portageand State of Ohio, have invented new and useful Im provements inMachines for Bending Fellies for Oarriage-VVheels; and I do herebydeclare the following to be a full and complete description thereof,reference being had to the accompanying drawings, in which-- Figure 1 isan end View of the machine, Fig. 2 a. side view, and Fig. 3 a top view.

Like letters refer to like parts in the different views.

A represents the frame work of the machine; B, the mounted formingblock. This consists of a half cylinder, having a dia-meter equal to thesize of the wheel which is to be made with the fellies. This halfcylinder forming block, B, is mounted at each end, upon a pair of truckwheels, C, which rest upon a track D, D, E, E, for the purpose ofconveniently moving it, under the bending apparatus. The mounted formingblock B, is five or six feet long, and is intended to be filled withfellies, the fellies remaining until they are dry enough to be removed.The block is filled by beginning at the end B, and bringing the b-lockforward, a suit-able distance, at each bending of a felly, until the`former is filled. It is then rolled forward until it stands entirelyupon the track E E. The track E, E, stands entirely upon another trackrunning at right angles thereto, and is seen in the several figures atF, F. The object of this track, is for the convenience of moving off aformer, when filled with bent fellies, so as to make room for another.IVhen the mounted forming block B, is shoved entirely upon the track E,E, this track E, E, can be brought over so that the rails E, E, willstand in connection with the rails G, Gr, seen in Figs. 1 and 3. Thistrack Gr, G, may be extended a sufficient distance to accommodate anydesirable number of forming blocks. After the fellies have been removedfrom the forming block B, these can be returned to the track D, D, inorder to be refilled.

The fellies are bent upon the forming block, by means of a band of iron,(I usually use hoop iron) in length equal to the length of the fellies,and which is represented at H, Fig. 4C. `A head I, Fig. t, is riveted toeach end of this band H, and upon the inside of each head I, is a seatJ, which re ceves the ends of the unbent fellies. The heads I, I, arepressed downward, and inward, by an arm L, which articulates in a movingfulcrum M, Fig. l, seen also detached in Fig. 5. The moving fulcrums M,are guided in their upward and downward movement, by posts N, whichreceive between them, a T head from the fulcrum VI. When the movingfulcrum l/I, is up, the arlns L lie nearly vertical, the lower anddivided ends, fitting into the steps O, O, Fig. et. As the movingfulcrums descend, the arms L, assume an inclined position as seen inFig. l, and thus press the heads I I, snugly to the sides of the formingblock. The moving fulcrum M, is drawn downward by cords P, I, which passaround friction rollers S, Fig. 6, and windlass Q, Figs. 2 and 6, thiswindlass being turned by a crank. The fellies when first bent, are heldin place upon the mounted forming block by grip'R, Fig. 4:, hooked uponthe heads I, between the steps O, O. The moving fulcrum M, is carriedupward by weights T, T, supported by pulleys and cords T, T.

The manner of using this machine, is as follows: The fellies are sawedor split, and shaved to a proper size, and cut square at each end, andjust long enough to enter the seat J, J, upon the inside of the headpieces I, I, the band H, being upon the outside of the felly. The fellythus prepared, is placed upon the mounted forming block B, and the rod Ubrought down firmly upon it, as seen in Fig. 1. This rod is attached toa lever V, whose fulcrum is at V', and the long arm of which is providedwith a clasp or cord, by which it can be firmly held in place. The shortarm is provided with a weight W, which raises the rod U, as soon as thelong arm of the lever is released from its fastening.

What I claim as my improvement, and desire to secure by Letters Patent,is,

The arrangement of the mounted forming block, and the system of tracksD, E, F, Gr, operating as described, when used in combination with theapparatus herein described, operating in the manner and for the purposeset forth.
